Given numbers are 260, 690, 432, 205
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(260, 690) = 17940
GCD(260, 690) = ( 260 x 690 ) / 17940
= 260 / 690
= 260
Step2:
LCM(10, 432) = 2160
GCD(10, 432) = ( 10 x 432 ) / 2160
= 10 / 432
= 10
Step3:
LCM(2, 205) = 410
GCD(2, 205) = ( 2 x 205 ) / 410
= 2 / 205
= 2
So, Greatest Common Divisor of 260, 690, 432, 205 is 1
